Asrock P45TS query

Hi! :wave

I have just bought this motherboard, (along with the Nvidia 9600GT graphics card) but, after connecting the PSU (Colors-IT 400w) up to it, I have no power! :cry

I've checked the power/reset/etc connections from case to mobo numerous times, but no luck. Do I need a more powerful PSU, or is there something I'm doing wrong?

Thanks in advance!

 

Can anyone give advice please?

Thanks.

 

Try another PSU but with much power the one you have is 0,and post back.
try cooler master exterme 460w.I had it and it's very good.
Also I have 9600gt.

 

I have just built a new PC with the ASRock P45R 2000 board and had a lot of trouble getting a screen and this may sound a bit silly but check that the cable from the screen to the GPU is seated correctly it the back of the PC.
I worked for 2 days before i found that the card was not exactly central where it protrudes from the back of the case and when i inserted the plug it had 1 pin shorting on the chassis.
Believe me i felt so stupid after blaming everyone and everything for the fault.

 

Thanks guys!

Was told to look at this:

CORSAIR CMPSU-450VX 450W ATX12V V2.2, but the price is a bit more than I had anticipated.

Was looking at something cheaper but with enough power for the board, 9600GT, a Q6600 and 2x 1GB OCZ DDR3 memory. As for storage. I currently have 2 Seagate 500GB Barracuda SATA II 300 7200rpm and a Samsung 500GB SATA II 300 7200rpm.

Thanks!

As for the GPU connection BILLMCC66, I've got an HDMI cable connected to the TV via a DVI to HDMI adapter. Would this make a difference?

 

Use the eXtreme PSU Calculator Lite to determine your power supply unit (PSU) requirements. Plug in all the hardware you think you might have in 2 or 3 years (extra drives, bigger or 2nd video card, more RAM, etc.). Be sure to read and heed the notes at the bottom of the page. I recommend setting Capacitor Aging to 30%, and if you participate in distributive computing projects (e.g. BOINC or Folding@Home), I recommend setting TDP to 100%. Research your video card and pay particular attention to the power supply requirements for your card listed on your video card maker's website. If not listed, check a comparable card (same graphics engine and RAM) from a different maker. The key specifications, in order of importance are:

1. Current (amperage or amps) on the +12V rail,
2. Efficiency,
3. Total wattage.

Then look for power supply brands listed under the "Good" column of PC Mechanic's PSU Reference List. Ensure the supplied amperage on the +12V rails of your chosen PSU meets the requirements of your video card. Don't try to save a few dollars by getting a cheap supply. Digital electronics, including CPUs, RAM, and today's advanced graphics cards, need clean, stable power. A good, well chosen supply will provide years of service and upgrade wiggle room. I strongly recommend you pick a supply with an efficiency rating equal to, or greater than 80%. Look for the 80 Plus - EnergyStar Compliant label. And don't forget to budget for a good UPS with AVR (automatic voltage regulation).

 

Hi Digerati.

Thanks for the link. Great tool.

It recommends a total wattage power of 438. Found no wattage requirements on Nvidia's site regarding the 9600GT though. Have seen comments though that a 500w PSU is more than enough! :cool

I know I'm being cheeky, but....would you recommend a particular brand of PSU?

Thanks!

 

Those from the good list above - that said, I have been using Antec supplies for years, but also like Corsairs and PC P&C.

 

Just read that a 500w PSU is sufficient. Also, both 9600GT connections (from card to PSU) needed to be connected to the PSU. As I don't have a dedicated PCI-E connection on it, would buying a PSU with one be better in the long run?

Thanks!

 

So are you saying you are not using both power connections? If not, you need to.

 

No! :-o

Didn't realise I needed to!

Will install new mobo & 9600GT (connected properly) and see if I get a signal!!

Would you mind if I let you know if I have sufficient power?

Thanks again!

 

I am sure it is in your manual.

Ummm, what?

 

Looked in the manual before trying to install it, but there was no mention of connecting both connectors.

The PSU I'm using now is a Colors-IT 400W Gold Silent and may not have sufficient power.

 

What is the brand and exact model number of that card?

You already proved that with the calculator.

 

It's a Zotac Geforce 9600GT 512MB DDR3 PCI-E.

 

Well, according the manual I found for Zotac cards, in Section 2, Step 7, it says,

This is further illustrated in Figure 2-2.

 

Looking at it again, I remember wondering if both connections were needed, or just the one as both connections are the same (Yellow, Black and Brown wires). :confused

Will have to get a PSU with a PCI-E connection if the PSU I have doesn't have the power.

Thanks again.

 

Because graphics cards are so power hungry - more so than CPUs - rather than stress the power circuits on the motherboard, many cards get power directly from the PSU. So it is better to get PSU designed for newer cards that supports these connectors (rather than using adapters).

 

So it looks like I'll have to spend more than I intended to for a PSU then? :cry

Oh well. Suppose it will last for a while!

Might look at the Antec's or Corsair's then.

Thanks very much for your help! :cool

 

Just remember the computer will draw from the wall what it needs, not what the PSU is capable of delivering. So, if your computer needs 425W, it will draw from the wall 425W regardless if the PSU is a 550W supply or a 650W supply. So buy for the future.

 

Thanks. I will do.

So a PSU with more wattage may not be more powerful?

 

Well, generally speaking, a quality 600W PSU from Good Company A is equal to a quality 600W PSU from Good Company B. But as I said, except for any difference in PSU efficiency, a computer draws what it needs, and the PSU supplies what its load asks for. The PSU is not pumping out full power full time jamming excess watts into the motherboard. If the computer (motherboard, CPU, RAM, drives and graphic card) only need 400W, that is all the supply will send it. Now you don't want to get a 400W supply because it will be running 100% full time and getting pretty warm with fan running loud and fast. Plus there would be no wiggle room in case you wanted to add an extra case fan, or another HD.

So you need some wiggle room for future growth quiet operation so a quality 500-600W is probably the minimum I would suggest for you. If you buy a budget $20 600W PSU, there is a darn good chance it was made in some dirty Chinese child slave factory overseen by corrupt government officials. Training and quality control are virtually non-existent, and who knows the quality of the parts used, or their suppliers. The voltages these supplies often supply are less stable, and "noisy" with lots of AC ripple - indicative of "inadequate" regulation, filtering and overhead.

"Invest" in a quality PSU along the lines of this supply. These supplies are much more likely to perform as promised, cool and quietly with no problems for years - 24/7/365 (except for periodic cleaning). They may still be made in China but with well trained and paid workers in clean factories using quality components, and decent quality control - necessary for any company that cares about their reputation and repeat business before putting their brand name on the product.

I like to put it this way - Would you put no-name generic gasoline in your new Ferrari? You might, but would you expect it to perform at top levels? An engine can misfire a couple times and keep on running - not so with with high-speed digital electronics. Don't feed your expensive CPU, motherboard, RAM and graphics card cheap power - it needs and performs on good, clean, stable power, under all possible load conditions.

Something else to chew on, and all too often forgotten - anything that plugs into the wall can kill! Get a good supply.

 

Thanks for ALL your help!

Sorry to be a pain! I have a limited knowledge of building PC's but, thanks to people like your good self, it is growing. Knowing what components work together is one thing, but knowing HOW they work is another! I have never been in this situation before (regarding PSU power) as it has never been a real issue for me. I suppose I have just been lucky! :-o

Once again, many thanks. You have been a great help. Really appreciate it. :major

I will go for a high end PSU. Probably a Corsair. Read good reviews about them!

Hope to speak to you again.

 

No, it is just the nature of the times. This is a graphics oriented world - getting more so everyday. It takes a powerful graphics solution to keep up. Interestingly, as graphics consumes more power, CPUs and power supplies are getting more "green".

 

Just wished they became more cheaper too!

 

Well, graphics cards can certainly be expensive ($3,049!!! - on sale too!) but monitors are coming down, and RAM too so that helps.
