Is my Power Supply enough for 15 HDDs ?

[TerryFawkes]

Hi everyone, here's my computer specs:

CPU: Intel i3 540
Mobo: Gigabyte H55 Ud2h
RAM: 4 stick 2x2GB DDR3
GPU: MSI Dual fan HD 7750
SSD: Plextor m5s 128gb
HDD:
- 2 x WD Blue
- 2 x WD Green
PSU: FSP Raider 550
FAN:
- 1 x 180
- 3 x 140
- 1 x 120 (LED)

I 'd like to buy more HDDs ( just WD Green ), for up to 15 HDDs for my computer. Of course, i have SATA expansion card (PCIe) and one thing i not sure is my PSU can handle enough power for that ?

For the cable, i use 4 pin molex to 4 SATA to expand HDD's SATA power connector, is that ok too ?

for 15 HDD you are looking at around 150 watt of power. http://www.tomshardware.com/reviews/desktop-hdd.15-st4000dm000-4tb,3494-6.html

what in the.. 15 .. lol .. about the psu i think it will NOT hold up.. the spin up consumption will mostly kill your psu but hey.. lets see if the others can say about it just wait

i'll buy 4 HDDs WD green next week, total is 8 HDDs. Can my PSU handle it?

If the number is 15 HDDs, should i change to SeaSonic M12II 620 Bronze 620W ?

I run 9 HD's now 3 Velociraptors, and 6 SSD's and my system pulls 681 watts at idle and caps off near 890-910 watts at full load, but that is including my entire rig.

I would say to be safe with 15 HD's I would not have anything lower then 1300 watts, or get a case that can take 2 PSU's 1 dedicated to the HD's and 1 for the rest.
