Possibly a bad PSU mistake?

Hi all I am building a computer at the moment with the specs in my signature. However the PSU I've ordered is Storm Silent LPG19-43 800W Power Supply (PSU). Now I've read a few reviews and there's mixed results to be honest. Some people saying its brilliant and others saying its terrible. All this kit is being delivered tomorrow so if need be I can get one from maplins or somewhere in an emergency. But does anyone have any actual experience with this PSU and if you did have a problem could it have possibly been down to that 1% that's faulty?

I only ask because let's be honest most people only leave reviews if they have a problem

Thank you very much
 
"It states the following on the PSU as well in regards to the maximum output of the PSU;

800W
+3.3V = 37A
+5V = 51A
+12V/12V = 20/23A
-12V = 0.8A
+5V SB = 2A

800W = +3.3V and +5V is 340W MAXIMUM output.

As such, based on this information, depending on what you are going to be doing with the PC, I would recommend a good quality 'branded' PSU. Corsair, Antec, PC Power, Silverstone, Kingwin, NZXT, Seasonic."

Edit: If it's going in that rig in your sig, DON'T! The PSU is the heart of any rig, there for should not be skimped on. I have no clue why people go spend $1000-1500 to make a fast and powerful rig, but then buy a low quality PSU to power it.

so PSU's are a tricky thing to buy. lots of cheap brands out there and you really do get what you pay for. Purely based on the fact this is so cheap its silly i'm going to say its a pile of crap.

If i can point you in this direction:

Go for a corsair 650tx or 750 or one of the other named brands in that sticky. The TX is the cheapest version of corsair but its still wayyy better than that other one.
 
Don't even attempt to run that your system on that peice of garbage.

It has no efficiency certification, and the specs on on scan.co.uk show that it has a single 12v Rail of only 32A. That means it's going to output only 384w for your cpu and card, plus any other components which require 12v. This is nowhere enough!

You want at least 38A for that card. Send it back and buy something worth-wile.

I'll let others recommend a suitable unit for you :)

Just so Bootup05 is clear, that's 38a just for the GPU alone.
 
There is this one I've found it's a 1000w which i know is too much but just because its rated 1000w doesn't mean it will run at that constantly surely? As far as I'm aware it will use only what it needs to. There are cheaper ones but this is the first gold rated one I've found:

Also I know I could get it cheaper but its just as the stuff is being delivered tomorrow I want to have it going by the end of tomorrow so online is sort of out of the question here. Unless anyone knows any decent computer shops in Worcestershire.

Yes, actually a good 650 watt psu will be enough to power that rig. For a single video card only though. If you plan on going sli later, you would need 750-850 watt unit.

Get a Corsair TX650 or XFX 650watt.
 
Well I am looking to get sli one day just when I have the money aha. Well after scan have messed up my order three times now its being delivered tomorrow now meaning I can order one online. Ideally from scan being that I'm currently sorting out a deal with them as compensation as I needed the stuff today latest.

This one is only single rail and only has 70A. I'm not to sure on how much power everything draws so would that be enough. Also it's 850w

@your first post - OMG that is the worst PSU ive ever seen - UNCERTIFIED OMG

Also this is a case study as to why wattage means f-all. Speak in amps my friend. Everything runs on the 12V system essentially, and by knowing how many amps it can put on that rail, means you can work out (by multiplying it by the voltage - in this case 12VDC), to get the wattage. Wattage is total, amperage is specific to the rail and more informative. Your crappy 800W PSU couldnt even deliver the

Plenty - you only need higher if you plan on 3 GPUs, or extreme watercooling and overclocking. I had 3 580s in mine everything watercooled and it pulled nearly a kW from the wall.

Your situation 70A is loads. That PSU would probably quite happily give you 80A.

Thanks so much. At the start of this project I thought I knew quite a lot about computers aha. Seems I know more software than I do hardware aha. These forums are really great though so thanks to everyone :)
