Server PSU replacement

[Jano]

I've just turned my HTPC into a server, and plan on popping in a few big HDD, but im not entirely convinced by the PSU I currently have, or it's ability to really power it safely and shut down should anything go wrong. This is the spec of the HTPC -

Microsoft Windows 7 Home Premium
OCZ Vertex 2E 60GB 2.5" SATA-II Solid State Hard Drive
Gigabyte GA-880GM-UD2H AMD 880G (Socket AM3) microATX DDR3 Motherboard
AMD Athlon II X3 Tri Core 445 3.10GHz (Socket AM3)
Samsung SH-B123L/BSBP 12x BluRay ROM DVDRW
BeQuiet Pure Power L7 530W Power Supply
HIS ATI Radeon HD 5450 512MB GDDR3 SILENT Low Profile PCI-Express Graphics Card
Scythe Shuriken BIG Quiet Low Profile CPU Cooler
OCZ Platinum 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz Ultra Low Voltage Dual Channel Kit

I've also got two 2TB HD's to add, and possibly a third. There is also a second 128gb SSD and its all in a Corsair 350D with a couple of extra fans.

Would the PSU be ok, or should I be getting something a bit more reliable?

It's more than enough. It has 420w on the 12v rails and with you using such a low power gpu I doubt that you would be pulling more than 120-150w in total.
