Can you guys help me choose between these two PSUs I think should be suitable for me.

Corsair HX620
CoolerMaster Real Power Pro M700

Running a fairly old P4 system which comprises of:
Asus P4C800ED Motherboard
Intel P4e 3.0GHz processor
1x 160GB IDE drive
3x 160GB SATA drives
1x DVDRW
4GB OCZ RAM (buying with upgrade)
Sapphire Radeon HD3850 AGP (buying with upgrade, maybe 3650.)
2x 80mm + 1x 120mm fans.
1x Floppy drive.
Couple of Lacie external hard drives, but they have own PSUs.


So the PSU needs to have all cables etc to power an older model computer, rather than a new dual core etc. At some point in the not too distant future I will move the guts of this PC to a media PC in the living room and probably take back this PSU to use in dual/quad core Intel based computer yet to be speced.

Noise, temperature and stability are all important to me as use the PC mainly for music production.



Also any suggestions on a quiet and stable graphics card with SD/HDTV out. Currently looking at Sapphire Radeon HD3650/3850 but worried they may be a bit noisy. Mainly used for video and some graphics out although some gaming isn't out of the question.


Thanks for reading.

My generic response would be Cosair > all

Yeah that's what I've been leaning towards for a while. Had a quick look at Zalman, Enermax and Nesteq but don't really see them being any better in any way.

I'm assuming any modern PSU is still compliant with an older, P4 ATX MB? Cosair is one of the few that mentions being compliant with the older standard as well as the new. Does only have 9 pin PCI-e sockets on it which worries it may limit my bigger upgrade when I get around to it in a few months though..
 
either of those are far more than you'll ever need. of the two id choose the corsair, but tbh you'd be fine with something in the region of 450-500w. 620w is enough for two high end cards in sli!
 
Well think I will stick with my original thoughts of Corsair but may go for one of the smaller ones.

Seen on another site they how have a 450 in the HX range and it has a 7 year warranty rather than the 5 years you get with the bigger units. Currently running on a 400W and don't think the PSU is the issue but it is getting noisy and it's always good to have a spare.

Partly overspeced it so much as it will transfer when I upgrade to quad core and heavier graphics etc in a fair few months (and my current PC takes back it's old PSU and becomes a media PC in the living room) so wanted something that would handle the omph delivered by quite a modern, hefty system (although still only running one graphics card, which seems to be the main drain.) My PC is mainly used as an audio workstation so does have professional audio card (RME HDSP9632) but don't think that really draws that much, few watts at most.


The power consumption calculator I have just seen posted by somebody seems to give consumption of under 400W even with a new quadcore and highest end graphics so maybe was a little over-worried with future-proofing but it's always best to overspec than underspec.
