I've just built another PC for someone and have noticed high readings from the PSU's +12V rail... It's always bouncing between 12.48v, 12.54v and 12.61v! Does this seem a bit high and can it cause lock ups and hardware failure? The PSU is a new 550W XFX Core Edition Pro (a re-badged Seasonic unit i believe).
I hope this is not going to be a major issue!
no thats perfectly fine generally they have a tolerance of a bout 10% either way. my coolermaster 700w is running at 12.288v i see that as it has more power to give if needed my last power supply was a 600w at running 11.5v when i changed it.Quote:

The XFX have been shown to run slightly high on the 12v esp if the 12v load is low and the 5v or 3.3v is high.
Stick it under load and you'll see those numbers tighten up.
I would use a multimeter you check the voltage readings. Software readings are not always accurate.
You're right! I've just been testing it with BF3 for the last hour and the 12V reading dropped to around 12.20V during gameplay... That's within the PSU's 5% tolerance (i'm sure it used to be 10% for PSU's a while ago). The 3.3V and 5V rails seem fine when idle and under load.Quote:

Club-3D Radeon 6850 (factory overclocked)
1TB Hitachi 7K1000.C HDD
Hey that's nearly better than mine and it's not an el cheapo system :P
Nought wrong with those specs it'll play games well, if you had an athlonII x2 and a 5770 then it'd be an cheap gaming system.
It's cheaper than a i5 2500k and a 6950 but that doesn't make it el cheapo.
If you put a system together for more than £200 it's not el cheapo
My PC is also a cheap'ish one... I say it's cheap because i used to be one of those people who spent over £1k on a new PC every 2 years, then i became wise :DQuote:

AMD Athlon II X3 455 (3.3Ghz)
Gigabyte GA-M68MT-S2P motherboard (Micro-ATX)
8GB DDR3 1333 RAM
1GB Radeon 5770 or 6770 (both the same)
500GB WD HDD (luckily i already have this!)
550W XFX Pro PSU
Fractal Design Core 1000 Micro-ATX case
Windows 7 64-bit
Should play games fine at 1680x1050 on a 20" monitor :)
