i've just bought a new Radeon HD5850
. Seems to be working fine, etc. BUT, when I turn the computer on, it sounds like .. hmm .. maybe the HD's try to spin up 3 times during POST. And POST always has some weird error .. but if I continue, then it's all fine.
So i'm wondering if my PSU is not powerful enough to handle what i've got in my box, now that i've replaced my old 8800GTS with this new 5850.
PSU = Antex True Blue 480W
CPU = Q8400 @ 2.66Ghz (stock, not OC'd)
Ram = DDR2 PC2-6500 2x2Gig (single channel :( stock, not OC'd).
Mobo: P5N-EM HDMI (nForce 630i/GeForce 7100 ... onboard graphics disabled).
HD = 2 :: 1x500Gig sata and 1x80gig sata.
Dvd = 1 x pata
other: usb mouse, ps2 keyboard, usb external HDD 500Gig.
So .. is there any way I can see if i need a bigger PSU without having to buy one and then test that out?
I think your symptoms are fair indicator that system needs more power.
Also, the PSU calculators are not reliable. – Sathyajith Bhat – 2010-07-24T12:18:31.367
@Sathya I think it's more an indication his PSU might be failing, personally. Hard drives and power supplies are the most mechanical and failure prone bits in any PC. – Jeff Atwood – 2011-09-25T08:20:09.600
